Ethereum Layer-2 Scams: How Fake Networks and Bridges Can Steal Crypto
Simran Mishra
Fake Ethereum Layer 2 networks can copy real projects, websites, RPCs, and bridges to make scammers’ networks look legitimate.
The danger starts when users bridge real ETH into a fake network. The fraudulent bridge can accept deposits while the promised L2 is not actually official.
A recent fake GIWA network reportedly attracted about 767 ETH from 1,335 addresses before around 766 ETH was drained from the bridge.
A familiar Chain ID does not prove a network is genuine. In the GIWA case, the fake network used Chain ID 9134 even though the real mainnet had not launched.
A working RPC, successful transactions, or a functioning blockchain also cannot confirm who controls the network. Attackers can create convincing infrastructure that looks real.
Watch for unofficial “mainnet live” claims, unknown RPC links, new bridge websites, urgent deposit requests, and networks missing from the project’s official documentation.
Before bridging, check the L2’s official website, launch status, Chain ID, RPC URL, bridge contract, block explorer, and contract addresses. Ethereum also recommends checking network information carefully before using a bridge.
Never give a smart contract unlimited spending access when a smaller limit is possible. Ethereum’s security guidance recommends setting spending limits to only the amount needed.
Already used a suspicious bridge? Stop interacting with it, revoke unnecessary token approvals, move remaining funds to a clean wallet if needed, save transaction details, and ignore anyone promising guaranteed crypto recovery.
